otherwise directed by the Owner.
11
C. Preparation of Planting Mixture:

sufficient planting soil mix where required to provide one foot (1') deep beds. Remove groundcovers and perennials from their pots immediately before planting. Handle plants carefully to prevent damaging roots. Place each plant in individual hole and firm the planting mixture around the roots. Groundcover plants may be planted after the pine bark mulch is placed.
G. Plant bulbs at the recommended depth and spacing typical to the area. Add bulb booster as the
bulbs are planted. H. Setting: Plant plants in pits. Set plants at such a level that, after settlement, a normal or natural
relationship of the crown of the plant with the ground surface will be established. Place each plant in the center of the pit unless otherwise directed. Plant plants in planting soil which has been thoroughly settled by watering and compacting. Form a shallow saucer at finished grade about each plant by placing a mound of topsoil around the edge of each pit or pocket. Do not use topsoil mixture in a frozen or muddy condition for backfilling.
I. Flood plants with water twice within the first 24 hours of the time of planting. Water at least twice
each week all plants during the maintenance period. Thoroughly saturate the soil around each plant at each watering. If sufficient moisture is retained in the soil, the required watering may be reduced.
J. Mulching: Immediately after planting operations are completed, cover all planting beds with a two
(2") layer of pine bark mulch. K. Absolutely no debris may be left on the site. L. Maintenance of newly installed plants will begin immediately after planting. M. Certification of acceptance and guarantee:
12
1. The Landscape Maintenance Contractor will request the Owner, in writing, for an inspection to determine whether the plant material is acceptable. If the plant material and workmanship are acceptable, written notice will be given by the Owner to the Landscape Maintenance Contractor stating that the guarantee period begins from the date of the Certificate of Acceptance.
2. Promptly remove dead and unsatisfactory plants from the project. Replacements will
conform in all respects to the Specification for new plants and be planted in the same manner.
3. Guarantee plants for a period of one (1) year after acceptance. Plants must be alive,
healthy and in satisfactory growth at the end of the guarantee period. A commensurate proportion of the planting contract will be retained and paid to the Landscape Maintenance Contractor after replacements have been made, one (1) year from acceptance of original planting.
4. At the end of the guarantee period, inspection will be made again. Any plant required under
this contract that is dead or unsatisfactory will be removed from the site. Each plant must show at least 95% healthy growth and have the natural character of the plant of its species in accordance with the American Nurserymen's Association standards. These plants will be replaced during the normal planting season, until the plants will live through one year. A final inspection for acceptance will be made after the replacement plantings have lived through one (1) year.
5. All replacements under the one year guarantee period will be plants of the same kind and
size requested by the Owner. The cost will be borne by the Landscape Maintenance Contractor, except for possible replacements due to vandalism, neglect on the part of others, or 'acts of God'.
